Not enough whites, blacks, or colors to make three separate loads.
Hooray! Laundry Thunderdome! Dump it all in one load and let it be Survival of the Fittest! A Texas cage match between the White Socks and the Black Tees! Will the eggshell turtleneck come out gray? Will this be my poor old knit top's last hurrah, tangling with the zipper of some jeans? Who knew laundry could be so much fun?
(I know, I know, somewhere my mom is crying. She taught me better than that...)
